SCATTERING OF FREE ELECTRONS WITH HYDROGEN ATOMS IN PROTON EXCHANGE MEMBRANE FUEL CELL.

This study examines the evolution of the Klein-Nishina (KN) cross section for hydrogen and platinum atoms in relativistic and non-relativistic scenarios. Using online MATLAB tools, the constructed model of KN cross section for both situations is calculated. The observation demonstrates that as electron energy increases, electronic and atomic KN cross section lowers, which lessens the relationship between the incoming electron and the target atom. The importance of atomic size is demonstrated by a comparison of the KN cross sections of hydrogen and platinum, with platinum possessing a higher cross section because of its greater size and more scattering centers. Higher atomic numbers result in greater interaction between sites and bigger cross sections, and they also play a role in this relationship. The variations in cross sections are also influenced by electron binding effects, especially in the instance of hydrogen. It is demonstrated that relativistic effects have a major impact on the KN cross section, including an exponential decline seen as the energy of electrons increases. In the relativistic domain, the electron's increased mass and decreased wavelength increase scattering probability and produce a greater cross section than in the non-relativistic case. This research sheds light on the variables affecting KN cross sections and their influence on radiation therapy, medical imaging, and materials science. [ABSTRACT FROM AUTHOR]
